What is the effect of the rule of review on "local" decisions?

'The effect of this conclusion upon the question immediately before us is clear. Because judicial powers may no longer be exercised by 'local agencies,' the factual findings of those agencies are entitled to no greater deference than those of other agencies lacking judicial powers under the Constitution. Accordingly we conclude that the rule of review which was reaffirmed by us in Bixby v. Pierno, supra, for application to adjudicatory decisions by legislatively created agencies of statewide jurisdiction is equally applicable to decisions by 'local agencies' as well.
